Subject: [PATCH] v-m/alertmanager: Suppress battery low alerts

The alerts for Z-Wave device batteries in particular are pretty
annoying, as they tend to "flap" for some reason.  I like having the
alerts show up on Alertmanager/Grafana dashboards, but I don't
necessarily need notifications about them.  Fortunately, we can create a
special "none" receiver and route notifications there, which does
exactly what we want here.
